We have developed a novel series of heteroaromatic BACE-1 inhibitors. These inhibitors interact with the enzyme in a unique fashion that allows for potent binding in a non-traditional paradigm. In addition to the elucidation of their binding profile, we have discovered a pH dependent effect on the binding affinity as a result of the intrinsic pK(a) of these inhibitors and the pH of the BACE-1 enzyme binding assay.
我们开发了一系列新型杂芳基β-分泌酶1（BACE-1）抑制剂。这些抑制剂以独特的方式与该酶相互作用，从而能以非传统模式实现强效结合。除了阐明它们的结合模式外，由于这些抑制剂的固有pKa以及BACE-1酶结合测定的pH值，我们还发现了一种对结合亲和力的pH依赖性效应。
